>>> %matplotlib inline results in SyntaxError: invalid syntax

I have installed Python 3.4.4 on XPSP3 and am trying to work my way 
through this tutorial.

A Complete Tutorial on Ridge and Lasso Regression in Python
http://www.analyticsvidhya.com/blog/2016/01/complete-tutorial-ridge-lasso-regression-python/

#Importing libraries. The same will be used throughout the article.
import numpy as np
import pandas as pd
import random
import matplotlib.pyplot as plt
%matplotlib inline

3.4.4 Shell...
